Skeeter Davis - The End Of The World
I wonder how much of the difference is due to munging by the studio, and how much was just due to having an orchestra behind her, if that's what it was. Her twang is also less pronounced on this one. Coaching? Soundboard magic? Or did she just use a different accent on the TV version?
There are a bunch of copies of this tune on YouTube, but the first few I tried were unembeddable because of the spoilsports at SME. That might be why there is ten seconds of silence at the beginning of this one.
